A shell is fired vertically upwards

[DriggyBoy]

A shell is fired vertically upwards with a velocity of v1 from a ship moving with a velocity v2, a person on the shore finds the motion of the shell parabola. Show that the horizontal range is 2v1v2/g

You know the formulas for the parabolic motion?

 

[DriggyBoy]

Sure ^_^
For the Range, the Time of Flight and the Max height :)

A hint: the problem is like the case in which the shell is fired inclined at a specific angle θ, the angle is to be arctag v1/v2.

 

[valerioperi]

Yes, because v1 is the velocity in the y direction and v2 the one in x direction.
